I mean, a translation of "et cum spiritu tuo" as "and also with you", or "Credo" as "we believe" isn't really a translation at all, is it?
I would encourage you to watch the Michael Voris video, Weapons of MASS Destruction. After that, I would also encourage you to read Pius X's encyclical, Pascendi, written back in 1907.
I am not certain that I buy a lot of the conspiratorial stuff that Voris has in his video, but the "Protestantation" of the Mass is very, very apparent. The soon-to-be-retired translation makes it far worse. Essentially changing the character of the Mass as a divine worship that is a figure of the divine worship currently going on in Heaven to a communal dinner.
I mean, look at the totally illicit acclamation: Christ has died, Christ has Risen, Christ will come again. Yes, that is a true statement...but its inclusion during the Eucharistic prayer has utterly nothing to do with the purpose of that Eucharistic prayer. (A re-presentation of the sacrifice at Calvary and offering the Sacred Body and Blood of Christ, a/k/a the Victim, as an oblation for the sins of the word)
They have managed to slide their modernist theology even more into the soon-to-be-retired mistranslation (even more than it is in the Novus Ordo mass in of itself). With a return to a more faithful translation from the Latin, some of the cards get knocked out. And a house of cards is very, very difficult to keep standing...particularly if one of the cards at the base is removed.
Lex orandi, lex credendi, lex vivendi.
You are so right that those are rotten translations. Two, only two, of the reasons it’s all being changed. Be happy!
